I/ "0 all whom it may concern Be it known that 1, PAUL M. HnNesTnN-BERG, a citizen of Germany, and a resident of lVilkinsburg, in'thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Connectors, of which the following is aspecification. V I

My invention relates to connectors a nd particularly to connectingdevicesfor 101D- ing electrical conductors.

One object of my invention is to provide a device of the above indicatedcharacter that shall be simple and durable in conf struction,economicalto manufacture, easy to manipulate and effective in operation.

Another object of my invention is to provide aconnector that shallpermit different numbers of conductors to be variously connected.

Another object ofmv invention is to pro-' n vide a connector that shallhave means io1 securely wedging a conductor thereagainst and resilientmeans for moving the wedging means.

A further object of myinvention is toprovide a connector that shall beprovidedwith longitudinal grooves and have readilyremovable means forsecurely 'wedgmg a conductor or conductors 1n the grooves.

' In practising my invention, 1 provide a end elevationalview thereof;Fig. 3. is a transverse sectional view of the device shown in Fig. 1,and Figs. 1 and 5 are side-elevational views of the device shown inFigs.1, 2 and 3, showing other arrangements of conductors connected thereto.

A member 1, which is preferably of hol-v low, cylindrical form but which.may be solid and of other cross sectional form and constructed frombrass, copper or other suitable material, is providedwith long-i-MANUFACTURING COMPANY,- A CORPORATION OF PENN- comvEc'ronQ Specificationof Letters Patent.

tudinal grooves 2 that extend between and slope to pomtson thesurfaceof, and removed from, the ends of the member 1.

Rings 3, preferably of rectangular crosssection, slidably embrace themember 1 and are forced apart, by a helical spring 4:, to ward lugs orstop members 5 at the ends of the member 1.

When the rings 3 are pressed toward each sloping endsof the grooves 2.-The device is extremely simple and durable in construction andeconomical to manufacture and facilitates the making of various formsand groupings of effective connections.

\Vhile I have shown and described a particular form of my invention,changes may be efi ected therein without departing from the spirit andscope thereof, as set forth in the" appended claims.

I claim as my invention-z l. A connector comprising an elongated memberhaving lateral projections at the ends thereof and a longitudinalchannel extending between positions removed from the ends of the member,longitudinally-movable members embracing said member, and a compressionspring extending between said movable members for moving the sameoppositely toward the ends of said elongated member and for forcingconductors against said elongated member at the ends of said channel,said projections limiting the movement of said movable members when theconductors are disconnected from said elongated member. I

2. A connector comprising a cylindrical member havinga plurality oflongitudinal conductor-receiving grooves extending between pointsremoved from theends thereof, longitudinally-slidable rings embracingsaid member,-- a helical spring embracing said member between said ringsto secure the conductors in'position, and means for limiting themovement of said rings.

3. A connector comprising a tubular mem ber havinga longitudinalconductor-receiving groove extending between points removed from theends thereof, longitudinally-slidable members mounted on saidnally-slidable members mounted on said member, a helical springembracing said tubular member between said slidable mem bers and meansfor limiting the movement of said slidable members.

'5. A connector comprising an elongated,

member having a longitudinal conductor-re ceiving groove extendingbetween points removed from the ends thereof, longitudinally-slidablemembers embracing said member and resilient means for pressing theslidable members toward the ends of the grooved member. 7

6. A connector comprising an elongated member having a longitudinalconductor-receiving'groove extending to a position removed from one endthereof, a longitudinally-slidable member embracing said member andresilient means for pressing the slidable member toward the said end ofthe grooved member.

7. A connector comprising a member having an elongatedconductor-receiving channel therein, said channel having a portionsloping to the surface of said member, and a member movable along saidsurface in the direction of said channel to secure the conductor inposition at the sloping portion of member having a longitudinalconductorreceiving groove extending to a position removed from one endthereof, a longitudinally-slidable member mounted on said member andresilient means for moving the slidable member toward the said end ofthe grooved member.

In testimony whereof, 'I have hereunto subscribed my name this 28th dayof Feb. 1919.

PAUL M. HENGSTENBERG.
